Ignores what may be full of rubbish (5)
I believe the answer is:
'ignores' is the definition.
The answer and definition can be both related to thinking as well as being verbs in their -s form.

I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for skips that I've seen before include "Waste containers" , "Large containers for rubbish" .)
